Aipplicatonled January 26, 132B. Serial No. 83,850. i

The present invention relates to certain new and useful imprfnements in metal doors .in which thc construction is simplilied and made possible at a lower cost without diminishing the strength, attractiveness or etliciency of the door. Among the further ob# jects of my invention are the following:

"l`o'provide a door `formed mainly of channel members rather than of tubular colistruction so that there is a greater facility in manufacture.

To afford a door of metal which when once tit will not warp, twister get out of shape.

To create a door having a kick plate atV the bottom to aid in opening the door, protect the bottom of the same and so arranged as to reinforcethe entire unit.

To provide a door which may have just enough wood or the like in the channel members to deaden the metallic sound if desired.

To provide a door constructed of channel members so that the frame may be thinner and narrower and thus permit of more center area.

A further object is to provide a door having channel members so arranged as to materially increase the stiffness and rigidity of the door, and provide a door which in prac-` tice will not weaken or unduly flex; and such other objects, advantages and capabilities as will later more iully appear.

1While I have shown in the accompanying' drawings a preferred embodiment of my ins ventioii, I wish it understood that the same is susceptible of modification and change wit-hout departing from the spirit of my iiivention. y

Referring to the drawings,

Fig. 1 is a vertical transverse section taken on line 1--1 of Fig. 2 and partly broken' .center panelling area.

in Figs. `1 and 4. A woodiiller or the like 64 shortdistance beyond the wood filler 6 if desired as clearly shown in Fig. 1 at 8. The 'f' side rails 3 `men'ibers 5 `which open inwardly so that the Aand are `formed of channel metal forming the closed side oi' the channel is exposed on the sideedges of the side rails 3 and Il as clearly shown in Fig. 3. These channel members 5 of the -side rails 3 and 4 may alsohave a wood filler (3 or the like 1 which may be slightly different in shape `than the fillers of the upper rail 1 and the lower rail 2, as clearly shown iiiF ig. 3. A kick plate 9 is secured to the bottom of the door by rivets or the like 10 as clearly shown in Fig, 1. Gripping or panel retaining members 11 joined to the channel members 5 hold the glass panel or other center iilling material 12 in place. Bolts or the like 13 may be used for clamping the gripping inembers 11. It will be seen in use thatwith the channel members of this invention, thinner and narrower top, bottom and side rails may be used, thus permitting of more glass or` It was heretofore necessary to use very heavy bottom, top and side members in order to hold the large center glass or paneled portion or portions safely and rigidly in position. By this invention I have eliminated these disadvantages and have produced a metal door made up of channel members instead of closed tubing, thus reducing the cost oi' production, without lessening the stiffness and rigidity of the door.

Having now described my invent-ion, I claim:

1. A door ctnnprising a lframework made up of metal channel members, the top and prising a pair ot' sheet metal plates connecting the outer faces of the intermediate and bottom channel members. Y

2.V A door comprising a framework made up of metal channel members, the top and bottom channel members oven on one end and the vertical side channei members opening inwardly with the closed edges of the same forming the two vertical edges of the door. an intermediate horizontal channel member spaced from the bottom channel member, and a kick plate secured to the intermediate channel member and the bottom channel member and comprising a pair of sheet metal plates connectingl their outer faces, and holding means associated with the top, intermediate and side channel members for retaining` in position a panel member.

8. A door comprising top and bottom sheet-metal channel members each having an open side, side channel members of sheet metal and a cross sheet-metal channel 1nem. ber disposed apart from but relatively close to the bottom channel member, all of said channel members being united to form a rigid fra-me, the inner portions of said top and sides and the upper portion of said cross channel member having inwardly extending 1,eee,eee

supports and a panel mounted therein and extending substantially the full length of the door from the upper channel member to the cross channel member, and two sheet metal plates connecting the outside faces of said cross and bottom channel members and formingr av metal kick plate :t'or the outersides of the door bottom.

4. A door comprising top and bottom sheet-metal channel members oi' relatively narrow dimensions, each having an open side, side channel members ot' sheet-metal ot relatively narrow dimensions, and a sheetmetal cross channel member disposed apart from but relatively close to the bottom channel member, all of said channel members being united to form a rigid frame, and a panel mounted between the top, sides and cross panel members and extending substantially the full length of the door, and sheetmetal plates substantially fiush with and attached to the exterior faces otl the cross and bottom channel members and forming a metallic kiek plate and panel for the bottom of the door.

In witness whereof, I'hereunto subscribe my name to this specification.
